Difference between wave velocity and particle velocity?

Consider a string tied toward one side and you are moving the flip side in your grasp. On the off chance that you painstakingly watch, the wave is flying out through the rope to the tied end. In any case, the particles, which constitute the rope move just in here and there bearing. They don't move parallel to the rope by any stretch of the imagination. In the event that that was the situation, after a touch of time, you would have had a rope that was denser on the tied end. So molecule speed is opposite to the wave speed in a transverse wave. It is equivalent to (omega) squared times the wave speed.
